I was toward the last engaged in screwing on a fixture for the generation of acetelyne gas.
"Darrow," said I, "there's one thing you've overlooked; you forgot to bring a cupola and a gilt weather-cock for this concern."
After the laboratory was completed, we put up sleeping quarters for the two men, with wide porches well screened, and a square, heavy storeroom. By the end of the third week we had quite finished.
Dr. Schermerhorn had turned with enthusiasm to the unpacking of his chemical apparatus. Almost immediately at the close of the freight-carrying, he had appeared, lugging his precious chest, this time suffering the assistance of Darrow, and had camped on the spot. We could not induce him to leave, so we put up a tent for him. Darrow remained with him by way of safety against the men, whose measure, I believe, he had taken. Now that all the work was finished, the doctor put in a sudden appearance.
"Percy," said he, "now we will have the defence built."
He dragged us with him to the narrow part of the arroyo, just before it rose to the level of the valley.
"Here we will build the stockade-defence," he announced.
Darrow and I stared at each other blankly.
"What for, sir?" inquired the assistant.
"I haf come to be undisturbed," announced the doctor, with owl-like, Teutonic gravity, "and I will not be disturbed."
Darrow nodded to me and drew his principal aside.
